"As an electrolyte, sodium is the positively charged ion on the outside of the living cell. Cations, anions, and ions exist in an exact balance outside and inside cells, so that a change in the balance of one or more cations or ions will cause a change in other cations and ions in order to maintain cell integrity. Simply put, sodium is responsible for regulating blood volume and blood pressure, although it serves other functions as well.
During a set of high-intensity muscle contraction blood pressure rises. This is a primary response of high-intensity training. During high-performance exercise, the metabolism of the body is better served by a higher blood volume since this translates into better oxygen and nutrient delivery to working cells. Just as importantly, a higher blood volume results in a more efficient removal of fatigue toxins."
